Application filed October 22, 1917, Serial 1 To. 19'7,863.

ToaZZ whom it may concern 6 it known that I, Mnrrriias Bacon, a citizenof the United States, residing at Boston, in the county of Suffolk andState of Massachusetts, have invented certain Inn provements in Machinesand lilethods for Use in. Shaping Upper-s, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indicating likeparts This invention relates to the manufacture of shoes and is hereinillustrated in its application to the making; of stichdown shoes. Itwill be recognized, however, that in many of its aspects the inventionis not limited to the manufacture of shoes of that particular type, butis generally applicable to the making of shoes of various kinds.

It has heretofore been dillicult and, in fact impossible from thepractical standpoint to produce a shoe of the stitchdown type in whichthe upper has the stretch removed and which is really lasted in thesense that the upper of a welt shoe is lasted; that is, one that hasbeen so stretched and shaped that it will retain its shape dur- 111;;long use as well as fit the wearers foot.

The preliminary molding of the torepart ot the upper by prior machines;such, for e:-;- ample, as that disclosed in United States Letters PatentNo. 1,170,405, granted Feb-- ruary l, 1916, on application of M. Brookand L. M. Brown, has contributed very r aterially toward the productionof a satisfactorystitch-down shoe, but nevertheless the upper has nothad the stretch. removed from it as thoroughly as is desirableiand as ispossible by the pullingover and lasting operations in the manufacture ofwelt shoes, for the reason, amongothers that in the prior machines theuppers are all treated alike and the different stretchingcharacteristicsof the individual upper are not taken care of. Moreover. in the lastingof the better upon a bed machine, the upper is wiped upwardly toward thesole of the shoe by thelasting wipers and thereby additionally stretchedand con formed to the shape of the last. No operations correspondingvery closely to the pull-' Specification of Letters Patent.

ing-over and bed lasting. operations formed on welt work have hithertobeen per-- formed in the. manufacture of stitchdown, shoes.

l A general object of this invention is to provide a forming machinewhich willsub- Y ject an upper to a treatment which will remove thestretch from. the upper. and conform the upper to the'shape required inthe finished shoe, the machine illustrated being adapted also to formon'the upper an out-- wardly directed sole attaching flange, thelocation of the angle of which with relation to the end and sideportions of the upper is not determined arbitrarily as in prior lna-qchinesby the size to which the upper has been: cut, but which isdetermined by the shape the upperisrequired to assume in the finishedshoe, including recedingor undercut" portions, and is formed inthe upperat the line of junction of the end. and sides ofthe upper with the sole,the angle beingformed.v in the upper after the stretch has een removed.irrespectively or" the size. to Which the upper has been originallyout. V A further object of the invention is to sub?! jee't theupperduring the. fo'rmingflopera tions to the action of heat; ofsuchquality as torender the upper soft and pliable during 0 thestretching operationsand to dry and set the upper in the shape. intowhich it is formed after the stretch is removed. f A feature of theinvention. consists in means for giving an upper a preliminary treatmentwhich will remove the stretch from the upper, and means for wiping theupper about the toe in a'direction'toward the plane of the sole, with orwithout means for forming the margin of the upper projecting beyond theplaneof the sole into an outwardly directed flange. In the machine meansisprovided for; a'ssum of the upper after the stretching" control 95.condition while it is being further wiped in the manner described.

A further feature of the sists in means 'for subjecting the upper duringthe described operations to. heat treatment such that during invention[con- '100 the stretching operation the upper will be" rendered hot andI moist, and during the final wiping operation and the fiangingoperation the upper will be dried and premanently set in the finalshape. Preferably also, means is provided for subjecting the upperbetween the stretching operation and the final wiping operation to anironing operation with or without the action of a drying heat to assistin removing wrinkles and drying out the upper prior to the final wipingand flange setting operations.

Another feature of the invention consists in a novel organizationcomprising a form shaped to correspond to the forepart of the last, andtoe embracing gripping jaws adapted to receive the upper in a substantially flat condition and having their gripping facessubstantiallyparallel to the plane of the-upper, together with means for effectingrelative movement of the form and the jaws in a direction perpendicularto the plane of the upper to cause the upper to be stretched and wrappedin stretched condition around the form, the upper in the machine shownslipping from between the jaws and being then disposed at its marginperpendieular to the bottom of the form which represents the plane ofthe sole in the coinleted shoe.

A further feature of the invention con sists in means for holding theupper margin in a position perpendicular to the bottom of the form, andmeans for wiping the upper at the end and sides of the form in adirectiontoward thebottom of the form and to shape the upper under theoverhanging portions of the form. In the machine shown the-re are alsoprovided means co-operating with the Wipers for forming the portion ofthe upper extending beyond the bottom of the form into a sole attachingflange.

In a further aspect the invention provides a novel method for use inshaping upper materials. In accordance with the practice hereinillustrated, the toe portion of the upper is molded off the last to giveit sub-' stantially the shape which it is to have in the finished shoeby drawing it over a form and wiping it heightwise of the form, afterwhich it is held from relaxing while its margin is shaped in accordancewith the requirements of the particular type of shoe which is beingmade. The upper may, as illustrated, be wiped repeatedly heightwise ofthe form; and its margin also may be subjected to successive treatments,for example in stitchdown work by ironing it in substantiallyperpendicular relation to the plane of the bottom of the form and thenwiping it outwardly to produce the flange characteristic of that type ofshoe.

These and other features of the invention, and the novel method referredto, will appear more fully from the following detailed description whenread in connection with the accompanying drawings and will be pointedout in the appended claims.

In the drawings,

Fig. 1 is a side view of a machine embodying this invention;

Fig. 2 is a plan view of the machine, which is herein shown as a doublemachine, one half being designed for operating upon a left shoe upperand the other half upon a right shoe upper;

Fig. 3 is a sectional view on an enlarged scale of the upper shaping andheat treating mechanism;

Figs. 4, 5, 6 and 7 are detail sectional views showing successive stagesin the operation of the machine upon a shoe upper; and

. Fig. 8 is a perspective view of a shoe upper after its treatment bythe machine.

Referring to Fig. 1 of the drawings, the numeral 2 indicates the frameof the machine in which are journaled adrive shaft i, and a cam shaft 6.Upon the shaft 6 are the came from which the movements of the variousoperating parts of the machine are derived, and also a suitable clutch 8operated by a treadle 10 by which the shaft 6 is permitted to receivefrom the drive shaft i a semi-rotation at each ope 'ition of thetreadle.

The machine is preferably double, that is, comprises two machinesoperated by separate treadles, the machine on one side being designed tooperate upon an upper 101 a right shoe, and the machine on the otherside being designed to operate upon an upper for a left shoe. It will beunderstood that upon depression of its treadle either machine may bestarted and will stop with the upper in final shaped condition, asillustrated in Fig. 7, and may be left any required time, for example,while the operator is placing an upper for the corresponding shoe in theother machine and starting it by operating the second treadle. The firstt-readle may then be depressed to start the first machine which willstop with the parts in open position and the upper released.

Since the halves of the machine are substantially identical, it will benecessary only to describe one side of the machine, it being understoodthat the other side is identical except that it is designed for shapingthe upper of a shoe for the other foot.

A last-lilre form 20 is provided to the shape of which the upper is tobe formed or molded. The form 20 is supported upon post 22 guided forvertical movement in the machine frame and arranged to be raised to movethe form vertically by a lever 24: pivoted at 25 between its ends andhaving at one end a pin and slot connection 27 with the post 22 and atthe other end carrying a cam roll 28 which travels in a path 29 surface.7 6 which embraces the form in close formed in a cam block 30. Across-head 40 is mounted on rods 42vwhich are arranged for verticalsliding movement in the machine frame, Upon the rods 42 be neath thecross-head 40 are shoulders 44 to effect positive raising of the cros-head, and on the rods 42 above the cross-head 40 are springs 46engaging at their upper ends adjustable abutments 48 upon the rods 42,through which springs the cross-head is yieldingly depressed. The lowerends of the rods 42 have pin and slot connections at 50 with a leverpivoted at 52 between its ends and having on its rear end a roll 54which engages a cam path 56 in-the cam block 30. is a jaw plate 60 whichembraces the toe portion of the form and is preferably formed adjacentto its inner edge with a rib or ribs 62. On the lower face of a part 63attached to the crosshead 40 is a corresponding jaw plate 64 which, whenthe cross-head is depressed by the mechanism described. grips theprojecting marginal portion of the flat upper against the jaw plate 60or against the ribs 62 when these are provided. This operation isclearly illustrated in Fig. 4.

The form 20 is next raised vertically and causes all parts of the upperabout the toe portion of the form to be stretched and wrapped over thetoe portion of the form, as illustrated in Fig. 5, the margin of theupper slipping from between the jaw plates 60, 64 and being thendisposed in a position perpendicular to the bottom of the form, that is,to the plane of the last bottom. During this treatment of the upper, theupper is subjected to moist heat, for example, by steam emitted fromorifices 66 leading from a chamber 68 formed in the part 63, the chamberreceiving steam from any suitable. tube 70. e

.As successive portions of the upper are being stretched and drawn fromthe jaw plates 60, 64, it is desirable that any wrinkles which may haveformed be smoothed out and the upper be partially dried before it isfurther treated. For this purpose the part 63 just above the jaw plateformed as a toe embracing ironing source through a flexible conformityto its end and side faces, as shown in Figure 2, and engages the upperas it is being drawn from between the stretching jaws and effects uponit a rubbing or wiping action, while subjecting it to, dry heat, due toheating of the parts by the steam in the chamber 68. Preferably means isprovided to press the margin ofthe upper against the ironing surface 76during its passage across that surface, not only to augment the ironingac tion of thesurface 76 but also to effect a On the machine frame, Fig.3,-

The inner portions of theseplates are cut away to permit the passage of the reduced upper end ofthe post 22 which supports the form 20. Between the plate 82 and ashoulder on the rod 22 is a washer 84 to provide a suitable bearing forthe plate-82; The plate 82 projects beyond the" form 20 and isbifurcated to receive the upper end of a lever 86 having therein a by apin 89 passing through the-bifurcations of the plate 82. The lever 86 ispivoted at 90 to lugs on the machine frame and its lower end isextending to the rear of the machine where itis pivoted to the upper arm94. of an angle lever fulcrumed and having on its other arm 96 a roll 97which engages an edge I block 30.

Since the wipers in the construction shown are not requiredto perform any overwiping of the upper upon the last bottom, theirmovement may be slight, beingas shown only suflicient to take care ofthe recession of the sides and toe end'ot the The wipers 110, 112 extendrearwardly oi the machine and are slotted at 117 to receive pins 121extending upwardly from a 'T-shaped slide 120 mounted for movementlongitudinally of the form 20 in the machine frame.

The slide 120 is bored to receive a plunger 122 having a pin and slotconnection at 124. with the upper end oic' the arm 9% by which theplunger 122 is actuated. Between the end of the plunger 122 and the endo'lf the bore in the slide 120 isa spring 3y which the slide 120 isactuated yieldingly from the plunger. ldositive retraction of the slide120 is elected from the plunger by means 01 a pin 128 which engages ablock 130 connected to the slide 120 by means of an adjusting screw Byadjusting the screw 132 the retracted position of the slide 120 andhence the open position of the wipers 110, 112 may be varied. its theupward movement of the form 20 rontinues the wipers 11), 112 areadvanced yieldingly through the mechanism descril to engage the upper onthe end and sides of the form and wipe the upper downwardly toward theplane 01 the bottom of the form, as clearly illustrated in 5 and 6. Whenthe plane of the bottom oi the term reached substantially the plane ofthe lower face of th wipers, Fig. 6, the plates 78, 80 are advancedthrough the mechanism already described to turn out wardly the margin ofthe upp extending across their edge faces to I m an outwardly extendingflange, shown in the time acting to gle between the form the upper intothe a end and side faces ot the rm and the top {MEGS of the plates '78,80. The machine stops with the parts in this position .to al low thestock to set in the shape into which it has now been formed. .lt will beobserved that the awipers receive the heat: conducted from the steamheated part 63 which assists materially in causing the up" per to setquickly in its molded term. The wiper plates 78, 80, being farther fromthe source Off heat and having greater radiating surface, are 1 esintensely heated than the ironing surface l6 across which the upper haspassed to effect partial drying out or the upper before the flangeturning and flange setting operations.

While this side of the machine remains in stopped position an upper maybe introduced into the corresponding mechanism of the other side of themachine and subjected to siilar operations. By the time this has beeneffected, the mechanism of the first side of? the machine may berestarted and the molded upper removed from the machine. Aiter thistreatment the upper will retain its form and is ready for attachment ofa sole or soles in the usual manner for completing the stitch-down shoe.

Since the movement of the form 20 is in fixed vertical path, it isdesirable to provide adjustment for the jaw plate 6 1 and the ironingsurface 76 longitudinally of th form. To effect this, the member 113 towhich the jaw 6 part 63 and the surface 76 are connected as described,is arrai en for adjustment relatively to the cross-head 10. The member113 has a rearward extension 1 10 havingan upwardly ex tending lug inwhich is rotatably mounted a screw 142 having threaded engagement withthe cross-head 4:0, as clearly shown in Fig. 3. By turning the screw themember 113 and its connected parts may be adjusted longitudinally of theform 20. Should this adjustment be suiiicient to interfere with theoperation of the wipers 110, 112, the screw 132 may also becorrespondingly adjusted to maintain the slots 116 and the wipers inproper relation to the rolls 118.
